2. According to the Paper Aircraft Association, a paper airplane thrown in space will not fly; it will float in a straight line. Unless it hits an object, it could literally float forever (see Resources). Wingspan 3. The record wingspan of a paper airplane is 40 feet and 10 inches. The craft flew over 114 feet before crashing into a wall. Education 4. Scientists, engineers and students use paper airplanes to study aerodynamics.
Any type of trauma or injury to the testicles can cause severe pain and discomfort. The most common mechanism of testicular trauma occurs from blunt trauma (~85%), which can occur from sports injuries, a direct kick to the area, car accidents, and straddle injuries.
The testicles are very sensitive; even a minor injury can cause pain or discomfort. Testicle pain may arise from inside the testicle or from the coiled tube and supporting tissue behind it (epididymis). So what causes pain in testicle?
